FoxxGB is a simple Gameboy written in C designed to be highly portable. Display and input are abstracted so that they can be tied into various devices without altering the emulation core.

• All CPU instructions
• Memory Management
• GPU timings with interrupts
• Timer with interrupts
• Input with interrupts
• Support for 32kb ROM only cartridges
• Background and basic sprite support

• Sound
• Advanced sprite functionality (Palettes etc)
• Full sprite priority support
• Stat interrupts
• Full cartridge support (MBC 1,2,3 etc)

To play a game simply drag the rom onto the executable.

FoxxGB requires the GLFW3 library to compile.

Directions = Up, Down, Left, Right
Start = Enter
Select = Space
B = Z
A = X
Close = Escape

The short answer: I was bored.

The long answer: I'd always wanted to make an emulator, but the task always seemed too much of a mountain to climb. I chose the Gameboy due to the obvious challenge, and excellent documentation surrounding the hardware. The choice was also motivated by CTurt's Gameboy emulator Cinoop (https://github.com/CTurt/Cinoop), the documentation for which helped me a number of times during development.

The emulator is still very rough and has not been completely tested. The only game likely to work is Tetris.
